For those patients undergoing biceps tenodesis, the tendon is tagged with a monofilament suture prior to detaching it from its superior labral attachment. The long head of biceps is then mobilized arthroscopically, and retrieved through an incision either in the groove (which is opened arthroscopically in the subacromial space) or at the inferior border of the pectoralis major tendon. A No. 2 non-absorbable suture is whip-stitched at the appropriate length. The remainder of the biceps tendon is excised and the anterior cortex of the proximal humerus is prepared using a cannulated reamer inserted into the bicipital groove. One suture limb is then passed through an appropriate size interference screw and the tendon is placed within the reamed tunnel. The screw is then advanced until it is flush with bone..
